TOSEPH SYLVAN, OF CHICAGO, ILLINOIS GLAZING BAR FOB SKYLIGHTS AND THELIKE.

I Application filed June 16, 1921. Serial No. 477,886.

To all whom it may concern:

Be it known that I, JOSEPH SYLVAN, a citizen of the United States, and aresident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Glazing Bars forSkylights and the like; and I do hereby declare that the following is afull clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in glazing bars for skylights andthe like and consists of the matters hereinafter described and moreparticularly pointed out in the appended claims.

One of the objects of the invention is .to provide a simple andeflicient glazing bar which may be made from sheet metal and which sogrips or clamps the marginal parts of the glass panels of the skylightas to form a watertight seal between the glazing bar and panel withoutthe use of putty or like material. 1

Other objects of the invention as well as the several advantages thereofwill more fully appear as I proceed with my specification.

In the drawings Fig. 1 illustrates a partial transverse verticalsectional view through a skylight construction embodying my improvedglazing bar.

Fig. 2 is a transverse vertical section on an enlarged scale, throughaglazing bar and the marginal parts of adjacent glass panels, the planeof the section being indicated by the line 2-2 of Fig-1.

Fig. 3 is a detail view illustrating the manner of introducing themargin of a glass panel into one of the glazing bar strips.

Fig. 4 isa perspective view of a fragment of glazing bar strip made inaccordance with my invention. I

Fig. 5 is a detail perspective viewof one end of a cap strip associatedwith my improved glazing bar.

In general my improved glazing bar includes -a channel or:V-shaped'sheet metal strip, the top part of one of the side members ofthe strip being bent to overhang but being-spaced from the top edge ofthe other side member-toprovide a laterally opening slotnearthe top of;the strip; This slot receives one margin of a glass panel and when thestrip rest with its bottom edge upon the stringers of a skylight and apanel'is entered into the slot, the weight of the panel will cause thestrip to rock or tilt laterally toward the panel about its bottom edge.When the strip is thus rocked, its top parts which definenthe slot,engage andsecurely clamp the top and bottom surfaces of the marginalpart of the panel.

Referring now in detail to that embodiment of the invention illustratedin the accompanying drawing, 10 indicates a truss forming a part of askylight structure which truss includes a horizontal bottom barll, anupright middle bar 12 and oppositely inclined roof rafters 13 which arefixed at their ends to the ends of the bottom bar and to the topend ofthe upright middle bar 12. Brace bars 13 are provided to connect themiddle parts of the roof rafters with the middle part of the horizontalbar which rests at its ends upon and is fixed 'to the usual curb walls14 (only one of whichis shown in Fig. 1) defining the sides of theskylight opening.

Connecting the trusses together are longi tudinal' top or innerstringers 15, bottom or outer stringers 16 and intermediate stringers17, all preferably made of angle bars. Secured'to the bottom andintermediate stringers 16 and 17 are combination or eaves gutter strips18 and 19 respectively and engaging both top stringers -15 isa one-pieceridge strip 20, said strips all being made of. sheet metal bent intosuitable form.

The combination or eaves gutter strip 18 includes a hooked flange 18which engages the stringer. 16 as shown, and two upright webs 18 -18respectively spaced from each other and forming stop shoulders for] thehooked flange 19 which engages the inter,-

mediate stringer 17: as shown, and two upright webs 19"--. 19respectively which are spaced from each other and form stop shouldersfor the outer ends of the top glazing bars 24 and top panels 25. In theweb 19 is a plurality of holes 19 The web 19 terminates in a verticaldepending hook flange 19 and said flange together with the web 19receives and holds a deflector plate 26 which prevents the wind fromblowing in through the openings 19 Between the hook flange 19 and theweb 19 the strip is formed to provide an outwardly opening groove 27 thepurpose of which will presently appear.

The ridge piece 20 has oppositely inclined side members 20* which arefolded upon themselves to form outwardly opening grooves 20 and hookflanges 20 which engage the top stringers l5.

- The glazing bars 2124c being identical in form and construction, adetailed description of one will suflice for both. Each bar is made upof a pair of substantially channeled or V-shaped sheet metal strips 2828and each strip comprises inner and outer sidewalls or members 29 and 30which are connected together along their bottom edges and divergeupwardly and outwardly therefrom. The inner side member 29 is of aheight greater than the outer side member 30 and its top marginal partis bent at substantially a right angle to form a web 31 which overhangsbut is spaced from the top edge of the member 30 to provide a. laterallyopening slot 32'of a width greater than the thickness 'of'the panel usedin connection therewith. The web 31 terminates in an upturned flange 33.n

The panels 22-25 are glass panels and are preferably of the kind havingthe ribs 34: on the underside arranged parallel with the glazing bars.The glazing bars 21 24 are shorter in length than their associatedpanels; the glazing bars 21 engaging at their ends against the shoulders18 and stringers 17 and the glazing bars 24 engaging at their endsagainst the shoulders 19 and stringers 15 respectively.

' To assemble the panels and glazing strips said strips are placed inpairs upon the sky light framing and are spaced apart a distancesubstantially equal to the width of the panels. One strip of each pairis then made to assume a substantially upright position as shown in Fig.3 when the margin of a panel is introducedinto'the slot 32. When thishas been done, the top. edge of the outer side member of the strip willengage in one of the grooves between adjacent ribs 34: on the undersideof the panel when the weight of the panel 'will cause the strip to tiltor rock laterally about its bottom edge until the outer edge of the web31 engages the top surface of the panel as shown in dotted linesin Fig.3. When the panels 2124 are in place the top end parts of the. top panelwill extend into the side grooves 20 of the ridge strip and the top endparts of the bottom panels will extend into the grooves 27 in the sidesof the combination or eaves strips 19. 3

Associated with each pair of glazing strips is a cap strip 35 whichincludes a horithe cap strip to pass, after which the flanges of theglazing strips engage the flanges" of the cap strip to hold them inplace upon the glazing bars. The top ends of the cap'strips extend intothe grooves of the ridge strip 20 and the combination or eaves strips19'respectively whilethe tail or outer ends 38 of the cap strips arebent about the flanges 18 19 of the eaves strips to secure the outerends of the cap strips in place. cap strips prevent any rain, snow ordust from passing in between the glazing strips, and the side flanges ofthe cap strips act to prevent any rain fromblowing or seeping in betweentheglazing strips and panels. The ends of the bottom part of the glazingstrips are cut away as shown in Figs. 1 and4 so that such water ofcondensation as drips from the margins of the panels and falls inbetween the side members of the strips, is discharged from the lowerouter ends thereof and passes through the openings 18 19 of the eavesstrips to be discharged upon the outside of the skylight. The webs 31and flanges 33 of the strips also provide gutters which discharge at thelower ends of the strip, such water as they may catch. 7

The improved glazing bar provides a water tight seal or connection atthe adjacent margins of the panels without the aid of putty or likematerial. They are made of sheet metal and therefore they decrease theweight which the skylight structure must sustain, and may be made at aless cost than Thus the the rolled glazing bars now in use. Noextraneous fastening means, such as bolts and rivets, are used in theassembly, consequentdefine a longitudinally extending slot along oneside of said channel like member, adapted to receive the marginal partof a skylight panel, said member being capable of a lateral rockingmovement about its bottom edge from an upright to an inclined positionunder the weight of the panel to cause the parts thereof defining theslot to clamp upon the marginal part of the panel.

2. A glazing bar comprising two chan nel-like members, each having sidewall parts arranged to define longitudinally extending slots alongopposite sides of said channel like members, adapted to receive themarginal parts of adjacent panels of a skylight, said members beingcapable of a lateral rocking movement away from each other about theirbottom edges from an upright to an inclined position under the weight ofthe panels to cause the parts defining the slots to clamp upon saidmarginal parts thereof of the panels.

3. The combination with a glazing bar comprising two channel-likemembers, each having side wall parts arranged to define longitudinallyextending slots along opposite sides of said channel like members,adapted to receive the marginal parts of adjacent panels of a skylight,said members. being capable of a lateral rocking movement away from eachother about their bottom edges from an upright to an inclined positionunder the weight of the panels to cause the parts thereof defining theslots to clamp upon said marginal parts of the panels, and a cap stripengaging the top parts of both 'of said members and covering the spacetherebetween.

l. In combination with a glazing bar comprising two channel-likemembers, each having side wall parts of different heights, the higherside wall part of one channel like member having a top web whichoverhangs and is spaced from the top edge of the other side wall part todefine longitudinally extending slots along opposite sides of saidchannel like members, each web terminating in an upturned flange, thesaid slots being adapted to receive the marginal parts of adjacentpanels of a skylight, both of said channel like members being capable ofa lateral rocking movement away from each other about their bottom edgesunder the weight of the panels to cause the parts thereof defining theslots to clamp upon the said marginal parts of the panels, and a capstrip having a web and depending side flanges, the

side wall parts of different heights which diverge outwardly from eachother from their bottom margins, the marginal top part of the side wallpart of greater height being bent to overhang but being spaced from theedge of the side wall part of lesser height to provide a longitudinallyextending slot along one side of the glazing bar strip adapted toreceive the marginal partof a skylight panel.

6. A glazing bar strip comprising two side wall parts which divergeoutwardly from each other from their bottom margins, the marginal toppart of said wall part of greater height being bent at substantially aright angle to form a web which overhangs but is spaced from the edge ofthe said side wall part of lesser height to provide a longitudinallyextending slot along one side of the glazing bar strip adapted toreceive the marginal part of a skylight panel, said web terminating inan upturned flange which is arranged in substantially the plane of oneof said side wall parts of the glazing strip.

In testimony that I claim the foregoing as my invention, I afiix mysignature in the presence of two witnesses, this 3rd day of June, A. D.1921;

JOSEPH SYLVAN.
